CORSET-STIFFENING.

SPECIFICATION forming part of Letters Patent No. 351,174, dated October 19, 1886.

Application tiled January 23,1886.

To all whom it may concern:

Be it known that l, llIARSHALL GARDNER, of Aurora, in the county of Kane and State of Illinois, have invented a certain new and useful Machine for Making Corset-Stiffening; and I do hereby declare that the followingisa full, clear, and exact description thereof, ref erence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an apparatus for man ul'acturi ng a peculiar stiffening for corsets or other garments, which stiffening consists of a series of stiffening-strips of whalebone, bamboo, or other analogous material arranged parallel with each other, and united by one or more layers of cloth or other flexible mate rialsuch, for instance, as is shown and described in a prior application, Serial No. 146,738, made by myself and James Stone, October 29, 1884.

The machine illustrated in the accompanying drawings as embodying the invention has been devised more especially for the manufacture of stiffening consisting of parallel bones and two layers of cloth secured together over the bones by an adhesive sub stance, as set forth in said prior application. Said machine embraces a pair of heated rollers, one or both of which are circumferentially grooved, between which rollers the two layers of cloth and the intermediate series of strips are passed for the purpose of pressing the whole together and uniting them into the pro- The machine also embraces various adjunctive devices, such as guides for the several layers of cloth, guides for the in terposed strips of bamboo, adjusting devices for regulating the pressure of the rollers, means for protecting the fabric being manufuctured from injury by heat of the rollers whenever it becomes necessary to arrest the machine with the fabric therein, and various other devices, which will be further explained. The apparatus as a whole also embraces a mechanism for applying the paste to the layers of cloth, and a system of guides by which the cloth is directed properly to the machine.

Serial No. 189,473. (No model.)

As a complete apparatus, it also embraces 5o mechanism for cutting up the product into pieces ready to be inserted in the garment.

The machine is illustrated as being provid ed with two sets or pairs of compression rollers or cylinders, each roller being provided with an interior gas-heating device to accomplish more perfectly the drying of the product and to fit it to be at once either cut into pieces for use or to be wound upon a roller.

In said drawings, Figure l is a side ele- 6o vation of the machine, showing the driving mechanism and presenting the machine in that view in which the product passes through the machine from right to left.

Fig. 16 is a perspective view of the part p shown in Figs. 16 and 16'. tion taken upon line at x of Fig. 16. Figs. 18 and 19 are views illustrating another and a preferred device for operating the knife at desired intervals. Fig. 20 illustrates a modified form of the device, which is hereinafter described.

A A are uprights or standards, arranged opposite each other in one or more pairs, and provided with vertical slots a a, affording guides for the bearingboxes B of the rollers or cylinders B B. In this instance two pairs of cylinders B are present in two sets of standards A, and for greater strength the two standards at each side of the machine are c011- nected by cross-bars ct. Said standards rest on a bed, A, having legs A, the feet of which are bolted to a suitable table. The bearingboxes of the upper cylinders of each pair are limited in their downward movement by stops c of any suitable form, on the standards, but have a possible upward movement, which is opposed by stilfsprings B, the tension ofwhich is adjustable by means of screws B B passing through arched cross-bars A A attached to the upper ends of the standards A,and extending over the slots a a. The bearing-boxes of the lower cylinders of each pair are sus tained by rods BB, which rest at their lower ends upon eccentrics O, mounted upon shafts 0, having bearings in brackets 0 bolted to the bed A, beneath the latter, these parts being so arranged that by the partial rotation of the shafts the lower cylinders may be raised or'lowered, as desired. Any suitable means may be provided for actuating the said shafts,

that herein shown consisting of a lever, 0 at-- tached to the end of one of the shafts, and connecting devices between the shafts, where by the rotary motion given to one shalt by the lever is transmitted to the other shaft. Means are desirably provided for locking the lever in position when the lower cylinders are raised, consisting ota spring-pin, c, Fig. 9, mounted in the end of a short arm, 0', upon the lever, and adapted to enter a recess, a", in a segmental arm, 0 bolted to the base A, as clearly shown in Figs. 1, 2, 3, 4, 7, and 9. The said arm 0 Fig. 17 is an enlarged detail secis, as shown, provided with a projection or stop, a, to limit the movement of the lever in lowering the cylinders.

The connecting device for transmitting motion from one of the shafts O to the other consists, as shown, of a pi vott-d and sliding lever,

0, connected at its opposite ends with cranks 0 upon the ends of the said shafts at one side of the machine, and provided in its middle portion with a longitudinal slot,c havingslidconveniently raised and lowered in inserting the materials to be operated upon between the upper and lower cylinders, as will hereinafter more fully ap pear.

The several cylinders B are geared together, so as to revolve at the same speed, by means of intermeshing gear-wheels B B upon the journals or trunnions I) of the upper and lower cylinders-0f each pair. and an intermediate gear-wheel or idler, B, Fig. 1, located between the gcarwheels B belonging to the two lower cylinders. Motion may be communicated to the cylinders for driving the latter in any convenient manner, a preferred construction for this purpose being herein shown, in which a a worm-wheel, D, is mounted upon the shaft of one of the lower cylinders, and is engaged with a worm, D. upon ahoriZont-ally-arranged shaft, D provided with suitable belt-pulleys, D, the said shaft D having bearing in asleeve, I), mounted to rotate about a vertical axis upon a standard, D", attached to the base A, whereby the said shaft may be swung in a vertical plane, and the worn thereby released from and engaged with the worm-wheel D at are united, the cylinders B are made hollowand are provided with interior gas-supply tubes, E, perforated for the exit of the gas, said tubes being inserted through the trunnions b, which are made tubular for this purpose, and sustained axially within the cylinders by means of arms or brackets E, Figs. 1, 2, and 7 .attached to the bearing-boxes B, and preferably provided with clamping devices e, of familiar construction, for engaging and holding the gastubes. The bracket E,adjacent to the trunnion supporting the worm-wheel D,is secured to the bar B", below the bearing B, as clearly shown in the drawings, Figs. 2 and 7. As herein shown, the cylinders B are made with separate metal heads b, cast integral with the trunnions b, and provided with apertures for supplying air to the interior gas-flame, Fig. 7, said heads being bolted to the cylinders, as shown.

The cylinders B are provided upon, their exterior cylindric surface with a series of equidistant circumferential grooves or depressions, b located at the same distance apart as desired for the bones in the finished stiffening, the intermediate ribs formed by said grooves being arranged to come together at the lines of contact bet-ween the upper and lower rollers of each pair, so as to force into contact with each .other the layers of cloth between the st-iffeningstrips during the passage of the said cloth and strips through the rollers, as clearly shown in Fig. 8. The grooves b in the upper and lower cylinders are made of such depth that they together form spaces or apertures of sufficient size to admit the passage of the strips at the line of contact of the cylinders, the grooves in the upper cylinders, as herein shown, being shallower than those in the lower cylinders, so that the grooves or depressions between the strips are made deeper, and the stiffening is given a more corrugated appearance upon one side than the other. This construction will usually be employed in order that the corset or other garment to which the stiffening is applied may be approximate ly smooth upon one side; but in carrying out the invention the depression of the cloth between the strips may be greatest upon one side or the other, or equal-1y upon both sides or wholly upon one side, as desired.

F F, Figs. 1, 2, 3, and 6, indicate curved guides or guards, over which the two layers ofcloth (indicated by G G) are trained in their passage to the pair of cylinders B, between which the cloth and stifiening-strips first pass in the operation of the machine, these being the cylinders shown at the right hand in Figs. 1, 3, and 13. Said guards F consist, as hereinshown, of curved metal plates, which are attached at their ends to the inachinestandards A A by brackets or arms ff, bolted to the said standards. The principal purpose of said guards F is to hold the cloth from contact with the heated cylinders until the several parts are about to be brought together between the latter.

The machine herein shown is more especially adapted for the manufacture of stiffening of the character above described of that class in which the stiffening strips are made of banr boo splints arranged in two thicknesses or layers, and said machine is provided with guide devices adapted to bring the separate splints or layers into proper relative position, and to direct the duplex strips between the layers of cloth and into place in the grooves of the cylinders. To these ends the said guide devices are constructed as follows:

I is a rigid horizontal cross-bar, attached at its ends to the frame-pieces A A, and supporting between the guide plates F the several parts which Operate to guide the strips.

1 is a guide-plate attached to the bar I, and extending inwardly toward the meeting-line of the cylinders B B, said plate being provided upon its upper surface with a series of upardly projecting guide -platcs, 6, arranged side by side and adapted to separate and laterally confine the several strips in their passage toward the cylinders. As herein shown, the guideplates t' are attached to the plate I. by having their lower edges inserted in grooves formed transversely insaid plate I, but said guide-plates may in practice be otherwise secured to the plate I, as found desirable or convenient.

The parts indicated by I" are a series of spring guide fingers attached at their outer ends to a cross piece, 1, which is sustained above and parallel with the plate I, the said fingers extending inwardly between the adjacent surfaces of the upper and lower cylinders. Said fingers are provided at their inner ends with depending flanges or wings t", engaging the opposite sides of the strips and resting at their lower edges upon thcsurface of thelower cylinder at both sides of the grooves I) therein,

' so as to guide the strips accurately into said grooves b, the extremities of said guide fingers being held forcibly in contact with the lower roller, so as to press or force the strips into the grooves of the said lower roller, together with the cloth carried to said lower roller over the lower gnideplatc, G, as clearly shown in Fig. 6..

l" l are a second series of spring-fingers attached to thcbar 1 over the fingers l, and extending inwardly over the plate l and terminating short of the ends of the fingers I said spring'fingers l being employed for the purpose of pressing downwardly into contact with the lower layers, H, of the stiffening-strips the upper layers, H, at a point above or adjacentto the plate I, the upper strips, H, being kept separate from the lower strips, H, by being guided over a cross bar, I", which is sustained by arms or brack cts l from the machine frame, Fig. 6. The horizontal plate I and guide platesi are preferably extended inwardly near 1y to the flanges or wings '1? upon the fingers l and the said plates i are extended upwardly in their inner portions, so as to engage and hold from lateral movement the fingers l and l. and to form lateral guides for the strips extending nearly to the guide-flanges t" of the fingers I.

To enable the extremities of the fingers l and l to be adjusted, vertically, so that said fingers will act with more or less pressure upon the strips, as desired. the bar 1, to which the fingers are attached, is rotatablysupported at its ends in lugs 1 upon the plate I, and is provided with a rigid arm, 6 adjustably connected at its free end with a part of the machine-frame in such manner-that the bar I may be partially rotated and held in its changed position, for the purpose above stated.

The particular means shown for adjustably connecting the arm t with the frame consists of a bar, i pivoted at one end to the said arm i and provided at its opposite end with a setscrew, i", adapted to bear upon the front margin of the plate I, as clearly shown in the drawings, Fig. 6. The plate I is in the particular constructio sh own detachably connected with the supporting-bar I, so that said plate and the several parts connected therewith may be removed from the machine, as may be required for cleaning the parts and for other purposes. A convenient means for securing the said plate I in place is illustrated in the drawings, wherein the bar l is shown as providedwith pins i which are fitted to apertures in a vertical flange upon the plate 1, which flange extends downwardly over the front of the bar I, said plate being held in place by levers or buttons D i, pivoted upon the bar I, near the ends of the latter and adapted to be turned so as to engage the ends of the said flange, as clearly shown in Fig. 2.

In the operation of the parts described the layers G G, previously coated upon theirad jacent faces with paste or other adhesive substance, are press'edinto contact with each other and with the strips between them by the first pair of rollers, which, as above stated, are heated for the purpose of rapidly drying the paste as the material passes between them. The passage of the stiffening between one pair of cylinders is not, however, usually found to' dry the paste sufficiently to permit the immediate cutting or handling of the stiffening. and the second pair of heated cylinders is there fore provided for more thoroughly drying the product.

The stiffening produced by the machine shown is illustrated in section in Fig. 8, and in side view in Fig. 10, G G in said figuresindicating the layers of cloth joining the stiffening-strips, and H H the separate bamboo splints or layers of which the strips are composed.

To prevent injury to the product by the heat of the cylinders, in case it becomes necessary to arrest the movement of the latter While the stiffening is being formed, horizontal guardplates J 'J, Fig. 3, are provided, which arearranged in pairs with one plate of each pair above and the other below the path of the product, said plates being attached at their ends at the sides of the machine to horizontallysliding bars J J, so arranged that when the cylinders are stopped and the lower cylinders dropped away from the upper ones, the said bars may be moved so as to carry the plates between the cylinders and the stiffening. The bars J. J are mounted to slidein suitable bearings upon the frame-pieces A A, as indicated at'jj, Fig. 7, and are preferably united at their rear ends by means of a rod,j, Figs. 1 and 3, which may be conveniently grasped by thehand in moving the guard-plates. The lower guardplate, J, between the pairs of cylinders obviously may serveto sustain the stiffening in a horizontal position in its passage from the;

first to the second of said pairs of cylinders. 7

The apparatus for applying paste to the layers of cloth before they are carried to the cylinders B B is illustrated in Figs. 11 and 12, and constructed as follows: K K are two rotating pasting cylinders or rollers c0nnected 8o sive substance employed forjoining the parts ofthestiffening. The said rollers are, as shown, driven by a worm, in, intermeshing with a worm-wheel, M, applied to the shaft of one of said rollers, the worm being formed upon a shaft, M, provided with suitable belt-pulleys,

M", loosely mounted upon the shaft, and connected therewith by a clutch device of simple form, indicated as a whole by M in the drawings. The continuous pieces or Webs, G G, of cloth, which form the cloth layers of the stiffening, are drawn from suitable receptacles, L U, or from reels, upon which they may be wound over suitable guide-rollers, L L located above the pasting-rollers K K, downwardly between said rollers, and then over suitably-located guide-rollers, as.L* L to the cylinders B B of them-achine, which forms the stiffening, the said cloth webs or layers being brought into contact with each other as they 'pass between said rollers, so that they are carried forward together by the latter, and each receives at the same time a coating of paste from the said rollers. I To prevent the cloth from adhering to the rollers, and to keep it flat and unwrinkled in passing from the lat ter, cylindric brushes K K, revolving in the same direction as the rollers K K, are located below the latter in position to bear upon opposite sides of the two layers of cloth. Said brushes are conveniently driven by means of idlers k 70, intermeshing with the gear-wheels It 70, and with suitable gears upon the brushshafts, as shown in Fig. 11. For removing surplus paste from the surfaces of the pastingrollers K, small rollers K K are arranged to bear upon the said pasting-rollers,-said rollers K K being, as herein illusti ated, mounted upon arms It It", pivoted at k k to the frame L, and sustained in proper position by set-screws It k connecting the outer ends of the levers with the frame, as shown, and serving as a means of adjusting the position ofthe rollers K when found desirable or necessary. The set-screws It, in the particular construction illustrated, are inserted through the arms 70 and engage a part of the frame L at their lower ends, and the set-screws k pass upwardlythrough blocks it upon the frame and abut at their ends against cross-bars in, uniting the outer ends of rro' the arms If. The rollers K" are preferably provided with pinions it intermeshing with the gear-wheels k k of the paste-rollers,whereby the said rollers K are given a positive rotary motion.

N N, Figs. 13 to 18, indicate the vertical side pieces of the frame of a cutting apparatus. (Shown in the sectional view, Fig.18, as located upon the base Ain proper position to operate upon the finished stiffening as the latter passes from the rollers B B.) The said cutting apparatus comprises, essentially, a series of revolving cuttingdisks, 0, and an opposing grooved roller, 0, operating to cut or slitthe finished stiffening longitudinally into strips of desired widths, and enacting stationary and reciprocating cutters 1 and P, located at the side of the cutting-disks 0, remote from the cylinders B, and operating to cut the strips formed by said cutters 0 into pieces or batteries of desired lengths. The diskcutters O are mounted upon a shaft, 0 Figs. 13 and 15, which, together with the grooved roller 0, is mounted in side pieces or castings, N, attached to the frame pieces N N. The shaft 0 and roller 0 are provided with bearings 0 0 0 0, the bearings 0 0 being secured by setserews a a in laterally-opening recesses n n in the castings N, and the bearings 0 being con-- structed to slide vertically in slots a 01*, formed in said castiugs,so as to enable the said grooved roller 0 to be separated from the cutting-disks O, as found necessary for adjusting the parts and for other purposes. The said bearings 0 0 are sustained by standards 0 which rest at theirlower ends upon eccentrics Q Q. mounted upon a shaft, Q, which has bearings in standards q q upon the base A, and is provided with an actuating-lever, Qf, (shown in dotted lines in Figs. 13 and 15,) constructed and op erating in the same manner as the lever 0*,

shown in Fig. 1, and above described. The shaft 0", supporting the cuttingdisks, and the shaft 0 of the roller 0, areprovided with intermeshing gear-whecls 0" and 0, motion for driving the cuttingdisks and the opposing rollers being transmitted to the shaft 0 by means of a worm-wheel, 0'-, fixed to the shaft,andaworm, 0, upon a shaft, 0*, provided with belt pulleys 0 as shown in Fig. 15 and in dotted lines in Fig. 13.

The cutting-disks O are made thin in their marginal portions, and sharpened upon their edges in a familiar manner, and are adapted to enter and fit closely in the grooves o ot' the roller 0', the said cutting-disks being mounted to move freely longitudinally. but not to rotate upon the shaft 0, so that they are held in proper position laterally solely by theirengagement with the said grooves. In the particular construction illustrated the cutting disks are made of thin sheet metal and provided with central hubs, which are fitted to slide upon the shaft 0 the latter being provided with a spline, 0 engaging suitable notches in the hubs, as clearly shown in the drawings, Figs. 13 and 15. The surface of. the

roller 0 between the grooves 0 is preferably depressed to form a second series of shallow grooves, 0 corresponding in size and distance apart with the grooves b of the lower cylinders B B. In the operation of the machine the stiffening passing from the said cylinders and over the roller 0 is seen red by the cuttingdisks acting in connection with the grooves 0 of the said roller along the spaces between the strips.

The lower knife, P, for cutting the stiffening transversely is secured at its ends to the vertical frame-pieces N N, and the movable or reciprocating knife 1 is attached at its ends to sliding blocks P P, heldand guided in vertical grooves n. formed in the inner faces of said framepieces, the ret'iprocaling knife P having an inclined cuttingcdge, and being arranged to move downwardly past the stationary knife in a familiar manner. The means shown foractuating the knife consists ofa shaft, P, mounted in suitable bearings, a" a, at the upper ends of the frame-pieces N N, and provided with eccentrics p, engaging yokesP, at tached to the upper ends of vertical bars P attached to the blocks P The shaft P is actuated by means of a belt-pulley, P, which is mounted loosely upon the shaft, said pulley and shaft being provided with a clutch device, whereby the pulley may be connected with and disconnected from the shaft, so as to cause the Operation of the cutter at desired intervals.

A clutchdevice of familiar form is shown in the drawings, Fig. 14, which is adapted to become automatically disengaged after a single rotation ofthe pulley and shaft, and after each downward i'novement of the rcciprocati ngkni fe P caused by such rotation. The said clutch comprises a collar, 1), mounted upon theshaft adjacent to the hub of the wheel P, and pro vided with one or more projections or stops, 1)", in its sidenearest said hub, aslidingspringdog. 19, mounted in the said hub in a position parallel with the axis of the shaft and adapted to engage the said stop f, a second radiallymovable spring-dog, 1), adapted to engage a notch in the dog 1)", so as to hold the latter in its retracted position and free from the said stop 12*, and a movable camplate, p Figs 14-, 16, 16, 16", and 16, provided with a laterallyinclined cam'face, p, adapted to engage the end of the dog p", so as to throw the latter iuwardly, and with a second outer inclined or cam-face, p Fig. 16, adapted to engage a lateral projection, 12, Figs. 15MB, upon the dog p, in such manner as to draw the latter outwardly, and thereby release it from engage ment with the dog p, said cam-plate being mounted upon a sliding rod, 1), arranged i 11 suitable bearings upon the frame-piece N radial to the center of the shaft, whereby the cam plate may be moved toward and from the said shaft. The said cam-plateisso constructed and located that when at the inward limit of its movement the inclined surface 1) thereof will be engaged by the dog 1), while the dog IIO 1f will freely pass the cam-surface p ,-and when said plate is at the outward limit of its movement the said surface p will engage and throw outwardly the dog 19', and the dog 1) will be allowed to pass the plate without contact therewith.

The relative position and operation of the parts above mentioned is more clearly-shown in Figs. 16, 16, and 16. In Fig. 16 the spring dog 19* is shown as engaged with the notch in the dog p so as to hold the latter at the inward limit of its movement and free from the stop, this being the position of the parts when the wheel P is running freely upon the shalt. In Figs. 16 and 16" the dogs 19 and p are shown in the position maintained by them when the wheel is connected with the shaft and with the canrplate p engaged with the said dog f, and in its position when about to move said dog for disconnecting the clutch. In this case the dog f is held at the outward limit of its movement by engagement with the outer surface of the dog 10 the spring which actuates Said dog p holding the latter against the said dog so that when the dog 19 is pushed back by the cam plate said dog 19 will engage the notch of the dog 19 When said dog 19" is at the outward limit of its movement, as above described, the projection p thereon is free from the cam-plate, which latter will at such time be at the inward limit of its radial movement and in position for the engagement of its lateral camsurlacep with the end of the dogp.

In the operation of the clutch device described the pulley, when rotating freely upon the shaft, as shown in Figs. 14: and 16. is connected with the shaft by drawing the camplate 10 outwardly, whereby the outer camsurl'ace, 29 is caused to engage and draw out-- wardly thedog 0', so as to release the dog 10 and allow it to spring into position to engage the stopp". If the cam plate is then immediately restored to its original position adjacent to the shalt, the end of the dog f, at the completion of one revolution of the pulley and shaft, will encounter the cam-face p, as shown in Figs. l6, l6", and will be thereby thrustinwardly until free from the pin 19, when it will be engaged and held by the dogp. Aspring, p, is connected with the rod 19 so as to hold the canrplate normally in its inward position, so that when the rod is released, afterbeing drawn outwardly to throw the clutch into engagement, the o1 utch will become automatically disengaged after a single rotation of the shaft. As herein illustrated, the spring 1) is attached at one end to the frame-piece N, and at its opposite end to a horizontal pivoted bar, S,

' through the medium of which, in the particua point between its pivotal point and its free end, is adapted to engage atsaid free end a pin, 8, fixedin arevolvingratchet-wheel, S, mount ed upona shaft, 8', having bearings in a suitable frame, S and actuated by means of a pawl, s, mounted upon the end of an oscillating arm, S Said arm is attached to a gear wheel, S*, which latter is actuated by means of a sliding rackbar, S", which is given a reciprocating movement through the medium of a rod, 8, connecting said rack-bar with a crank pin, 8 securedin a rotating disk, S, actuated by suitable gearing from one of the cylinders B, the said crank-pin 8 being adjustable radially in thcdisk, so as to enable the throw of the rack-bar, and consequently the extent of rotation of the wheel S at each revolution ot'the disk, to be changed as desired. By adjusting the position of said crank-pin the said wheel S may obviously be given a complete revolu tion during a greater or less number of rotations of the disk S, so that the pin 3 will e11- gage and move the bar S, and thereby cause the operation of' the cutter more or less frequently, according to the length of the pieces it is desired to cut from the stiffening. Inlhe particular construction of the parts illustrated the disk S is actuated by a gear-wheel inter meshing with one of the gears B of the upper cylinder B, Figs. 13 and 17, and the pin 8 is secured in a T-groove, s, in the face of the said disk by the familiar construction illustrated in Fig. 17

Another, and for some reasons a preferred, construction in a device for regulating the length of the pieces or batteries cut from the stiffening by the cutters P P is illustrated in Figs. 18 and 19. In this case the lever S is depressed at desired intervals to actuate the clutch device by means ofa series of knobs or studs, t, secured at equal distances apart upon a belt, T, which is trained over two pulleys, T T, mounted upon suitable bearings at the sideof the machine-frame. In the particular construction illustrated the pulley T is sestandard, T .upon the bed A in such manner that the pulleys T and T may be separated or brought together to provide for longer or shorter belts. The stud t is, as shown in the drawings, shouldered and provided with a nut, P, to enable it to be readily moved in the slot t and secured in its changed position in thesaid slot. In the use of this device the frequency with which the cutter P is operated will obviously be determined by the distance apart of the studs it upon the belt, so that by placing a greater or less number of studs upon the belt or by using belts of different lengths, in case this is necessary in order to enable the'studs to be spaced equally at desired distances apart, pieces of stiffening of.

desired lengths may be accurately cut by the machine. The bar S is in this case desirably provided with a movable projection or stud,

.9 arranged in position for engagement with' the studs 1. upon the belt, and adapted to be shifted upon said bar S as found necessary in changing the distance apart of the studs t or the length of the belt and position of the pulley T In the construction shown in Fig. 18 the spring 1) is shown as placed around the rod 19 instead of being connected with thebar S, as is the case in the construction illustrated in Figs. 14 and 16.

The device for regulating the operation of the cutters P (shown in Figs. 18 and 1.), and last above described) has important advan tages in point of simplicity of construction and operation, and is therefore made the subject of specific claims herein.

It is entirely obvious that the same result as is accomplished by the grooved cylinders B B may be cdected by a pair of cylinders, one of which is provided with grooves sufficiently deep to receive the full thickness of the strips, and the other of which is smooth or without grooves, as illustrated in Fig. 20, in which the upper cylinder B is shown as smooth, and the lower cylinder contains a series of grooves, b. The product in this case will obviously be flat upon one side. It is to be understood, therefore, that the term grooved cylinders, as employed in the appended claims, covers a pair of cylinders consisting of one grooved and one smooth cylinder, .well as the two grooved cylinders described, and also that said machine may be employed in constructing stiffening in which single strips are secured to one layer instead of between two layers of flexible material, the grooved rollers B B obviously operating, in case only one layer of cloth is present, to hold the strips parallel with each other and to press them into con tact with the said layer of cloth in a manner readily understood. In making stiffening of the character last mentioned, opposing rollersone of which is smooth and the other groovedwill usually be employed, such asis illustrated in 20, and above referred to, in which is illustrated a stiffening made of single strips H and a single layer of cloth, G.

It has been found thatin making the stiifening above described, especially in the use of thin cloth for the layers G G, that paste is liable to strike through the said layers so as to come in contact with the heated rollers, and thereby cause the cloth to stick to said rollers. I have discovered that this difficulty may be remedied by applying a coating of paste to and allowing it to dry upon the cloth before the latter is fed to the machine, the paste being moistened as it passes to the rollers by jets of steam or otherwise. By this means the moist paste is prevented from striking through the cloth by reason of the body of dried paste which fills the latter; but the process mentioned is objectionable, as requiring an addi tional handling of the material used for the layers, and a better Way of avoiding the difficulty mentioned is to prepare the paste by mixing therewith a small quantity ofparafline, which I have found to effectually prevent the cloth from sticking to the cylinders. By this means not only is the necessity of first drying the paste on the cloth and then moistening it avoided, but the paste may be applied by a pasting device, as herein described and shown, whereby the cloth may be pasted and the stiffening complcted continuously and by a single operation.

The stiffening-strips employed in making the stiffening, as hereinbefore set forth, will usually be fed tothe machine in continuous lengths or strands, formed by securing together, end to end, pieces of the usual length obtainable by glue or otherwise, the stiffening-strips, in the case of bamboo, (the material most commonly used,) usually being obtained in pieces about twelve feet long.

In carrying out my invention as it relates to the machine described, adhesive substances of a kind which do not, like paste or glue, require immediate drying to cause the stiffening to retain its form may be employed, and in such case devices for heating the grooved rollers or for applying heat otherwise to the stiffening may be dispensed withas, for instance, an adhesive cement having sufficient body or consistency to hold the layers and strips in proper position without being dried may be employed, the cement in such case be ing allowed to dry after the stiffening is com pletcd; or a rapidly-drying substance may be employed,which will become sufficiently hard to retain the parts in place during the passage of the materials through one or two pairs of rollersas, for instance, a solution of shellac in alcohol.
